Logistical Aspects of Different Online Teachinglearning Methods Among Medical Students During COVID-19 in a Tertiary Care Teaching Hospital, Thrissur, Southern India

Due to the Coronavirus Disease-2019 (COVID-19) lockdown implemented by the government, we had to transform our classes into the online sphere. The most commonly used methods of online teaching in Government Medical College, Thrissur were, live online lectures, PowerPoint presentations with narrations, prerecorded videos and assignments. Aim: To assess the logistical aspects, merit and demerits of different online teaching-learning methods among phase-1 medical student in a tertiary care teaching hospital during COVID-19 lockdown Materials and Methods: This cross-sectional study was conducted from July 2020 to September 2020, among phase-1 MBBS students of Government Medical College, Thrissur, Kerala, India. Data was collected from 161 students through a questionnaire consisting of two parts. The first part dealt with logistical aspects, like net connectivity, gadget, expenditure, financial burden, residence and eye strain with online teaching learning methods. The second part dealt with the merits and demerits of each type of teaching learning methods, according to the students. All statistical data was analysed using the Statistical Package for the Social Sciences (SPSS) software version 16. Qualitative data was expressed as a percentage. Results: A total of 97.5% population of students was able to frequently access the online classes. Online learning strained the eyes of 47.8% of students. Mobile phones were used by 92.5% of students for attending online classes internet connectivity was mainly through 4G (71.4%) followed by Wi-Fi (19.9%) connections. Their most preferred method of online learning was online live lectures (35.4%) followed by PowerPoint presentations with narrations (33.5%). Blended learning (online and traditional together) was best preferred method of learning (46.6%). Conclusion: Live online lectures and blended learning were preferred by the majority of students. Thus, the online classes can be continued along with the traditional teaching in future

Human Genome-Wide RNAi Screen Identifies an Essential Role for Inositol Pyrophosphates in Type-I Interferon Response

The pattern recognition receptor RIG-I is critical for Type-I interferon production. However, the global regulation of RIG-I signaling is only partially understood. Using a human genome-wide RNAi-screen, we identified 226 novel regulatory proteins of RIG-I mediated interferon-β production. Furthermore, the screen identified a metabolic pathway that synthesizes the inositol pyrophosphate 1-IP7 as a previously unrecognized positive regulator of interferon production. Detailed genetic and biochemical experiments demonstrated that the kinase activities of IPPK, PPIP5K1 and PPIP5K2 (which convert IP5 to1-IP7) were critical for both interferon induction, and the control of cellular infection by Sendai and influenza A viruses. Conversely, ectopically expressed inositol pyrophosphate-hydrolases DIPPs attenuated interferon transcription. Mechanistic experiments in intact cells revealed that the expression of IPPK, PPIP5K1 and PPIP5K2 was needed for the phosphorylation and activation of IRF3, a transcription factor for interferon. The addition of purified individual inositol pyrophosphates to a cell free reconstituted RIG-I signaling assay further identified 1-IP7 as an essential component required for IRF3 activation. The inositol pyrophosphate may act by β-phosphoryl transfer, since its action was not recapitulated by a synthetic phosphonoacetate analogue of 1-IP7. This study thus identified several novel regulators of RIG-I, and a new role for inositol pyrophosphates in augmenting innate immune responses to viral infection that may have therapeutic applications

Paying for Hemodialysis in Kerala, India: A Description of Household Financial Hardship in the Context of Medical Subsidy.

INTRODUCTION: Many low- and middle-income countries are implementing strategies to increase dialysis availability as growing numbers of people reach end-stage renal disease. Despite efforts to subsidize care, the economic sustainability of chronic dialysis in these settings remains uncertain. We evaluated the association of medical subsidy with household financial hardship related to hemodialysis in Kerala, India, a state with high penetrance of procedure-based subsidies for patients on dialysis. METHODS: Patients on maintenance hemodialysis at 15 facilities in Kerala were administered a questionnaire that ascertained demographics, dialysis details, and household finances. We estimated direct and indirect costs of hemodialysis, and described the use of medical subsidy. We evaluated whether presence of subsidy (private, charity, or government-sponsored) was associated with lower catastrophic health expenditure (defined as ≥40% of nonsubsistence expenditure spent on dialysis) or distress financing. RESULTS: Of the 835 patients surveyed, 759 (91%) reported their households experienced catastrophic health expenditure, and 644 (77%) engaged in distress financing. Median dialysis-related expenditure was 80% (25th-75th percentile: 60%-90%) of household nonsubsistence expenditure. Government subsidies were used by 238 (29%) of households, 139 (58%) of which were in the lowest income category. Catastrophic health expenditure was present in 215 (90%) of households receiving government subsidy and 332 (93%) without subsidy. CONCLUSIONS: Provision of medical subsidy in Kerala, India was not associated with lower rates of household financial hardship related to long-term hemodialysis therapy. Transparent counseling on impending costs and innovative strategies to mitigate household financial distress are necessary for persons with end-stage renal disease in resource-limited settings

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Microbiota regulates the turnover kinetics of gut macrophages in health and inflammation

The gut immune system has evolved to co-exist in a mutually beneficial symbiotic relationship with its microflora. Here, using a germ-free fate-mapping mouse model, we provide clear insight into how the enteric commensals determine the kinetics of macrophage turnover. The microbiome density along the gastrointestinal tract defines the persistence of ontogenically diverse macrophages, with the highest numbers of the long-lived F4/80hiTim4+ macrophage subset in the less densely colonized small intestine. Furthermore, the microbiome contributes to a tightly regulated monocyte-dependent replenishment of both long- and short-lived F4/80hi macrophages under homeostatic and inflammatory conditions. In the latter situation, the commensals regulate rapid replenishment of the depleted macrophage niche caused by the intestinal inflammation. The microbial ecosystem imprints a favorable cytokine microenvironment in the intestine to support macrophage survival and monocyte-dependent replenishment. Therefore, the host immune system-commensal cross-talk provides an efficient strategy to assure intestinal homeostasis.Ministry of Education (MOE)Published versionThis work was supported by a Ministry of Education Tier1 grant awarded to C Ruedl

Transient blindness due to ketamine anaesthesia in a child

We report a 10 years old male child apparently normal till he suddenly developed generalised edema and decreased urine output of 10 days duration. A renal biopsy was done under aseptic conditions with Inj Midazolam and Inj Ketamine given for anaesthesia. The child complained of blindness after waking up. The blindness was transient and lasted for about 30min. Child’s vision completely recovered. Renal biopsy was suggestive of rapidly progressive glomerulonephritis (RPGN). Treatment was started with intravenous highdose methylprednisolone, intravenous cyclophosphamide and mycophenolate as mainstay medication. Thetreatment was rapidly effective with immediate decrease in anti-GBM titres and plasma creatinine. On follow up, the child has normal kidney function, blood pressure and no residual disease. This case report is to stress on an extremely rare side effect of ketamine, a commonly used anaesthetic drug for short procedures

Neurogenic pulmonary edema in a child with status epilepticus

Neurogenic pulmonary edema (NPE) is defined as acute pulmonary edema after a sudden neurologic insult. It develops after a significant central nervous system insult such as trauma, hemorrhage or seizures and can occur both in adults and children. A 6-year-old male child, known case of cerebral palsy was brought to the emergency department in status epilepticus. He had severe respiratory distress with pink frothy secretions pouring from the mouth. Clinical and radiological examination was suggestive of NPE. Child was immediately ventilated and all supportive measures were started. Child showed marked improvement within 48 h of admission with diuresis and positive end-expiratory pressure (PEEP) assisted ventilation

Differential gene expression analysis of <it>in vitro </it>duck hepatitis B virus infected primary duck hepatocyte cultures

<p>Abstract</p> <p>Background</p> <p>The human hepatitis B virus (HBV), a member of the hepadna viridae, causes acute or chronic hepatitis B, and hepatocellular carcinoma (HCC). The duck hepatitis B virus (DHBV) infection, a dependable and reproducible model for hepadna viral studies, does not result in HCC unlike chronic HBV infection. Information on differential gene expression in DHBV infection might help to compare corresponding changes during HBV infection, and to delineate the reasons for this difference.</p> <p>Findings</p> <p>A subtractive hybridization cDNA library screening of <it>in vitro </it>DHBV infected, cultured primary duck hepatocytes (PDH) identified cDNAs of 42 up-regulated and 36 down-regulated genes coding for proteins associated with signal transduction, cellular respiration, transcription, translation, ubiquitin/proteasome pathway, apoptosis, and membrane and cytoskeletal organization. Those coding for both novel as well as previously reported proteins in HBV/DHBV infection were present in the library. An inverse modulation of the cDNAs of ten proteins, reported to play role in human HCC, such as that of Y-box binding protein1, Platelet-activating factor acetylhydrolase isoform 1B, ribosomal protein L35a, Ferritin, α-enolase, Acid α-glucosidase and Caspase 3, copper-zinc superoxide dismutase (CuZnSOD), Filamin and Pyruvate dehydrogenase, was also observed in this <it>in vitro </it>study.</p> <p>Conclusions</p> <p>The present study identified cDNAs of a number of genes that are differentially modulated in <it>in vitro </it>DHBV infection of primary duck hepatocytes. Further correlation of this differential gene expression in <it>in vivo </it>infection models would be valuable to understand the little known aspects of the hepadnavirus biology.</p
